Definitions
- the present invention relates to a non-woven mat of acrylic continuous filaments.
- the present invention relates to a non-woven mat of continuous, parallen and monodirectional acrylic filaments having a high modulus, particularly suitable for use as reinforcement of inorganic matrices, such as cement, plaster, mortar, concrete etc., and organic matrices, such as bitumen, thermosetting resins, etc.
- inorganic matrices such as cement, plaster, mortar, concrete etc.
- organic matrices such as bitumen, thermosetting resins, etc.
- acrylic fibres having a high tenacity and a high elasticity modulus in the form of short fibres from 30 to 60 mm, single or adhesively bonded by cement, mortar, bitumen or thermosetting resin is known.
- a reinforcement having all the above-mentioned characteristics is a non-woven mat comprising one or more overlapping layers, each comprising continuous, parallen and monodirectional filaments of an acrylic polymer and showing a tenacity of at least 50 cN/tex, an elastic modulus of at least 1,000 cN/tex and an ultimate elongation of less than 15 %.
- the non-woven mat of the present invention has a very spread structure to allow an easy penetration thereof by the matrix to be reinforced.
- the layers which constitute them non-woven mat are preferably crossed layers, providing a homogeneous reinforcement along the two normal directions.
- the number of layers preferably is at least 2 and depends on the stress the finished manufactured article will be subjected to.
- Non-woven mats containing up to 1000 overlapping and crossed layers can be used.
- Each layer may have a weight of from 10 g/m2 to 200 g/m2, preferably of from 20 to 50 g/m2.
- Filaments of each layer have a diameter varying from 8 to 50 ⁇ m and can be bonded to each other either by suitable agents or by sewing.
- the cohesive agent is chosen according to the intended use of the mat, the agent being compatible with the matrix to be reinforced; furthermore, in some cases, it is required that this agent be soluble in the matrix so that the filaments are not bonded to each other after the matrix impregnation.
- the cohesive agent is selected from the ones which dissolve or swell in water or in the alkaline solution of such matrices.
- the cohesive agent is preferably of the type soluble in organic solvents such as ethylene glycol, styrene, toluene etc.
- the cohesive agent is preferably insoluble and not meltable under the conditions used to produce the reinforced article.
- agents which dissolve or swell in water and can by used are: carboxymethyl cellulose, polyvinyl alcohol, polyacrylic or polymethacrylic acids, polyvinylacetate showing a medium or high degree of hydrolysis, acrylic and/or methacrylic copolymers (water soluble or emulsifiable), copolymers containing an alkylacrylate, and alkylmethacrylate and an unsaturated carboxylic acid and so on.
- Examples of cohesive agents soluble in organic solvents are: polyurethane resins, polyester resins, epoxy resins and so on.
- Examples of cohesive agetns insoluble and not meltable are: urea-formaldehyde resins, melamine resins, grafted acrylic resins and so on.
- the amount of cohesive agent to be used depends on the diameter of the filaments, on the number of filaments to be bound per width unit and on the type of the cohesion agent used. Generally, the amount ranges from 5 to 50 %, and preferably from 10 to 20 % by weight, based on the filaments.
- the cohesion of the filaments of each layer can also be achieved by a sewing transversal to the filaments at a distance of 2 to 15 cm. This allows to have a higher interaction surface between filaments and matrix to be reinforced, because the staples of the filaments are practically all free.
- filaments of acrylic polymer comprises the ones obtained by wet or dry spinning of acrylonitrile homopolymers or copolymers, containing at least 90 % by weight of acrylonitrile, the remainder being an ethylenically unsaturated monomer copolymerizable with acrylonitrile, such as methyl methacrylate, methyl acrylate, vinylacetate, styrene, vinylchloride etc.; preferably, these polymers have a specific viscosity ranging from 0.1 to 0.6.
- An acrylonitrile homopolymer is particularly preferred.
- the non-woven mat of the present invention can be produced according to a process comprising the following steps:
- the thus obtained non-woven mat may be used for the reinforcement of inorganic or organic matrices of the above-mentioned type.
- the resulting reinforced manufactured articles show low brittleness and high impact resistance, along with high tensile strength values. Said properties cannot be obtained when short fibres, such as asbestos, glass or short organic fibres, are used as the reinforcing material.
- the tow was stretched 7 times in hot water, dried under stress at 180°C, the dry-stretched a further 2 times, cooled and collected in boxes, avoiding any twisting.
- Each single filament had a tenacity of 70 cN/tex, an elastic modulus of 2,200 cN/tex and an ultimate elongation of 9 %.
- This tow was then continuously fed into a machine consisting of: - a series of straight bars alternating with curved bars on which the tow was spread under stress until it reached a width of 1 meter; - a series of spray nozzles metering a 20 % by weight aqueous solution of partially hydrolized (90 %) polyvinylacetate, with a flow rate such that a 15 % content of adhesive, based on the fibers, was provided; - a hot-air circulation drying chamber (at 150° C); - a system for winding the thus obtained layer on a spool.
- a machine consisting of: - a series of straight bars alternating with curved bars on which the tow was spread under stress until it reached a width of 1 meter; - a series of spray nozzles metering a 20 % by weight aqueous solution of partially hydrolized (90 %) polyvinylacetate, with a flow rate such that a 15 % content of adhesive, based on the fiber
- the layer consisting of continuous, parallel, monodirectional and bonded filaments, had a weight of 23 g/m2 and such a consistency as to allow easy handling thereof in the operations of cutting, overlapping the layers and impregnation thereof with the matrix to be reinforced.
- the layer was used to produce a continuous "mat", 1 meter in width, consisting of 6 overlapping layers, with a sequence of the type 00-11-00, wherein 0 means a layer of filaments parallel to the longitudinal direction of the web and 1 means a layer of filaments perpendicular to the longitudinal direction.
- 0 means a layer of filaments parallel to the longitudinal direction of the web
- 1 means a layer of filaments perpendicular to the longitudinal direction.
- the edges of the thus obtained multilayer "mat” were sewed 1 cm in width on each side to ensure a good dimensional stability and an easy handling of the mat.
- the three kinds of slabs were covered with polyethylene films, kept for 24 hours at room temperature, then dipped in water for 7 days and finally allowed to ripen at 20°C (at 100% relative humidity) until the 28th day.
